To /tZZ whom, it may concern:

Beit known that I, JOHN J. HERBRECHT, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Heaters, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in heaters, and particularly to the upright sectional class for low-pressure steam or hotwater service, one object being to so construct and arrange the several sections as to yield the greatest heat efficiency with the least possible amount of fuel by causing the water to travel in shallow bodies along tortuous paths and over an extensive heating-surface.

The further objects of this invention are to facilitate circulation of the water or steam and to permit either of the sections to be readily removed and another section replaced without disturbing the remaining sections or the steam and return drums.

vTo this end the invention consists in the construction and arrangement of the parts of a sectional heater, as hereinafter fully described, and pointed out in the claims.

Referring to the drawings, Figure l is a perspective view of my improved sectional heater. Figs. 2, 3, and 4 are sectional views taken, respectively, on lines 2 2, Fig. 1, and 3 3 and 4; 4, Fig. 2. Figs. 5 and Gare isometric Views, respectively, of the detached front and rear sections as seen from their inner faces. Figs. 7 and 8 are similar isometric views of the detached bridge-wall section,looking from its rear face, and one of the intermediate sec tions, portions of Fig. 8 being broken away for showing the interior partitions in the water-legs.

Similar reference characters indicate corresponding parts in all the views.

This invention. consists of front and rear sections A and B, a bridge-wall section C, intermediate sections D, interposed between the front section and the bridge-wall section, and one or more additional sections E, interposed between the bridge-wall section and the rear section, all of which are formed hollow and 0f the same general outline and are arranged face to face, one in advance of the other, and are mounted on a suitable base F, having the usual ash-pit and grate. Each of these sections are so constructed as to establish a complete and independent water and steam circulation within itself from its extreme low point to its upper apex and to divert the heat ed water from the sides of the combustionchambcr over more intensely heated surfaces and concentrate the steam-globules toward the apex or outlet of the sections. These va rions sections each comprise an upper chamber 1, having depending water-legs 2 2 and a central hollow portion 3, communicating at their upper ends with the chamber l, the Water-legs 2 2 being extended beneath the lower face of the central portion 3 for forming the side walls of a combustion-chamber 4 and the central portion 3 being extended beneath the upper ends of the water-legs and formed of less width than the distance between said water-legs for forming a hollow crown-sheet 5 and u pwardly-diverging branch fire-passages (i G of the combustion-chamber.

The upper wall of the chamber 1 of each of the sections is provided with a discharge-opening 7, each of which is connected by a detachable nipple 8 to a suitable steam-drum G. The lower ends of the water-legs of each section are provided with inlet-openings 9, di- Verging downwardly from the lower ends of their outer walls, and are connected by independent detachable nipples l0 to oppositelyarranged return water-drums H. These return-drums are preferably arranged with their upper faces in a plane beneath the lower end faces of the water-legs in order that any one of the sections may be readily disconnected from the drums G and II and Withdrawn laterally over either of the returndrums without displacing the remaining seetions or the steam and return drums.

The lower ends of the side walls or waterlegs of the several sections adjacent to the base F are preferably inclined inwardly t0- ward each other, which gives a neater appearance to the heater and slightly increases the heating-surface of the combustion-chamber. The hollow central portion 3 of each 0f these sections is provided with one or more substantially central fire-dues, which extend from front to rear of the sections in a plane beneath the upper ends of the fire-passages G 6 and forms said central portion with a IOO shallow conduit between the combustionchamber and fire-flue having upright portions 7 7, communicating with the chamber 1, and a downwardly-curved lower portion S, which forms a shallow water containing crownsheet for the combustion-chamber and firepassages, the lower curved wall serving to deflect the heated products upwardly toward the upper ends of the water-legs and into the branch fire-passages 6 6.

The adjacent faces of the marginal walls of the combustion-chamber 4 and fire-passages 6 6 of each of the several sections are disposed in substantially the same plane, and it is thus evident that the adjacent faces of the crown-sheet of each section lies in substantially the same plane as the corresponding faces of its water-legs and that when the sections are properly assembled the products of combustion are confined between the waterlegs and prevented from reaching the fireflues except through channels provided therefor and hereinafter described.

In order to facilitate the circulation of the expanded water from the crown-sheet of the central portion 3, the cross-sectional areas of the water-passages through the upright portions 7 7 are gradually increased upwardly to the point of union with the chamber 1.

The parts of my improved heater relating to the upright sections thus far described are common to all of the sections; but the parts hereinafter specified relate more particularly to their combinations and individual construction.

The intermediate sections C, D, and E are preferably formed with lower, intermediate, and upper tire-fines 12, 13, and 14, the liues 13 and 14 being previously referred to as extending through t-he central chambers 3, and the ues 12, consisting of the upper portion of the combustion-chamber and openings, eX- tending through the bridge-wall section C and the additional section E, both of which will be presently described. The portion of the front section between the water-legs 2 and the central portion 3 is preferably of less depth from front to rear than the water-legs and extends downwardly to the lower ends of said water-legs for forming the hollow front wall and a portion of the crown-sheet of the combustion-chamber and the upwardly-extending iire-passages at the sides of the central portion 3. The front section A is also provided with a fuel-opening 15, extending through its front wall beneath the central portion 3 and is also formed with a tire-Hue 16, previously referred to, which connects the front ends of the intermediate and upper flues 13 and 14 of the intermediate sections withV each other, the front end of the iiue 16 being closed by a Suitable door 17. The portion of the rear section between its water-legs and the central portion 3 is also formed of less depth from front to rear than the waterlegs, extends downwardly to the lower ends of said water-legs, and forms a hollow rear wall of the combustion-chamber. This construction of the rear section forms a portion of the crown-sheet and tire-passage 6 6 of the combustion-chamber and also serves to counect the rear ends of the lower and intermediate fines with each other. The main fireiiue of this rear section is alined with the upper fire-fines of the remaining sections and discharges into a suitable smoke conduit or chamber 1f), which in turn is connected to a chimney. (Not illustrated.)

The bridge-wall section C and the section E are each provided with hollow transverse base portions 20 and 21, connected to their respective central portions by suitable upiowconduits 22, which extend across the lower iiues or fire-passages, said portions 20 and 21 having their opposite ends connected to their respective water-legs.

The hollow transverse base portion of the section C forms the bridge-wall of the combustion-chamber, for a purpose well known and unnecessary to further describe, and usually extends beneath the corresponding base portion of the section E to thelower end faces of the water-legs.

The intermediate sections C are all of substantially' the same construction, their lower portions between their water-legs being cut away for forming the main portion of the combustion-chamber. Any number of these sections C may be used for increasing ordiminishing the heating capacity of the heater, it being understood that the front and rear sections A and B and the sections D and E are used with any number of the sections C.

The intermediate sections C, D, and E are each provided with one or more upflow-conduits 24, extending across the intermediate fire-line 13 and connecting the lower shallow conduits of the central portions 3 with transverse conduits 25,which connect the opposite upright hollow walls of said central portion between the lire-fines 13 and 14.

In order to properly distribute the water rising in the water-legs, I provide each of the intermediate sections C, D, and E with oppositely-arranged series of conduits 26, the conduits of each series being arranged in planes one above the other and having their outer ends connected to the water-legs and their inner ends inclined upwardly and connected to the opposite walls of the central portion 3. The upper walls of the outer ends of these conduits are preferably extended into the water-legs, partially across the water-passage therein, for forming partitions in said legs and diverting a portion of the uptlow water through the conduits and to the central portion 3. These partitions preferably project outwardly from the walls of the legs adjacent to the combustion-chamber, the upper partitions or deectors being extended into the water-legs a greater distance than the next lower partition. This feature of myinvention is particularly important, since it is well known that the water adjacent to the IOO IIO

inner walls of the legs is heated to a higher degree,and therefore expands upwardly more rapidly, than the portion of the water more remote from the colnbustion-chamber, and that if allowed to continue upwardly in said legs, thereby receding from the source of heat, a local circulation is established in the waterlegs and the distribution of the heated water is retarded, thereby causing undue waste of fuel and time in obtaining a proper circulation through the distributing-pipes and radiators. These partitions or deiiectors are designed to obviate this waste of time and fuel and serve to deflect the first-expanded Water in small volumes directlyover the combustion chamber, where the same is additionally heated and expanded through the shallow conduits of the central portion 3 and is readily discharged as steam or highlyheated water through the enlarged upper chamber l into the steam-dru rn and tothe distributing-pipes.

The operation of my invention will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be noted that the transverse conduits 2G of the intermediate sections are formed ot` less width from front to rear than the corresponding width of their water-legs 2 and intermediate chambers 3 for permitting the fire to pass upwardly from the combusion-chamber and to impinge against the upper walls of the lire-passages It will be further noted that the front section is provided with clean-out openings 30,which are alined with the spaces between the transverse conduits 2G for permitting the surfaces of said transverse conduits and the walls of the fire-passages G to be cleaned when desired.

The rear section is generally provided with a supplemental or direct draft-line 31,extend ing through its hollow base portion beneath the Hue ll and connecting the combustionchamber directly with the smoke-chamber 19.

One of the primary objects of constructing the various sections with upwardly-extending fire-passages between the water-legs and the central chamber is to produce a high combustion-chamber, which not only divides the hollowsections into a series of shallow water-containing chambers, but also increases the firesu rface of said sections and renders the heater more eflicient in producing steam and augmenting the circulation of the water.
